pro one will. artist with vst add-on will also work. prime (free one) won't work with external VST instruments, I believe.
don't have personal experience with Sonuscore, but I use free Kontakt player with my S1 pro. in Pro there're more sounds and instruments included, but the Kontakt player is a welcome addition to this sound palette. in fact I use some instruments from Kontakt, some from native library, some from other plugins and they all sound different.
